The Friends of Lake Sonoma welcomes you!

The Friends of Lake Sonoma is a cadre of volunteers that supports the interpretive and educational programs managed by the U.S. Army Corps of Engineers at Lake Sonoma.  Due to federal budget shortfalls, we also provide funding to help maintain the park and keep key facilities -- including the Milt Brandt Visitors Center -- open to public access.  We welcome your help -- financially through monetary and in-kind donations or through your service as a park volunteer! 

The Ranch at Lake Sonoma's trail rides are all the rage

The Ranch at Lake Sonoma is up and running -- and seeing Lake Sonoma on horseback is just fantastic.  The views are splendid and the experience is first-class. For a really unique trailride, schedule a Park Ranger Guided Tour.  Be sure to bring your camera.  This is an opportunity to see the park like you've never seen it before!
